How to safely upgrade Bash on AlmaLinux and roll back if needed?

I need to upgrade the Bash package on an AlmaLinux system while minimizing risk and preserving the ability to roll back if the update causes problems. I plan to back up configuration files and possibly take a system snapshot, but I am uncertain about the best practices for selecting which files to back up, how to verify the new Bash version works correctly, and what reliable methods exist for rolling back to the previous version using the package manager’s history or restoring from a snapshot. What steps should I take to ensure a safe upgrade and a dependable rollback?
